NSTALLATION
:
STEP 1.
Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way
when the venting system is attached. If this is the case, you may want to adjust the location of the
appliance.
STEP 2.
Direct vent pipe and fittings are designed with special twist-lock connections. Assemble the desired
combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall
or floor, as much out of view as possible.
Place a bead of Mil-Pac on the
outer edge of the inner exhaust
pipe (non-flared end). Place a bead
of high temperature silicone on the
male edge of the outer pipe. Push
the pipe sections completely together,
then twist-lock one section clockwise
approximately 1⁄4 turn, until the two
sections are fully locked. The female
locking lugs will not be visible from the
outside, on black pipe. They may be
located by examining the inside of the
female ends as shown in Figure 8.
Notes:
(1)
Twist-lock procedure: four indentations, located on the female end of the pipes and fittings, are designed to
slide straight onto the male ends of adjacent pipes and fittings, by orienting the four pipe indentations so they
match and slide into the four entry slots on the male end.
(2)
Horizontal runs of vent pipe must be supported every three feet. Wall straps are available for this purpose, also
when running horizontal pipe minimum clearances to combustibles must be maintained;
2 inches (5.1 cm) at
top, 11⁄2 inches (3.8 cm) at sides, 11⁄2 inches (3.8 cm) at bottom.
STEP 3.
With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4 cm) x 10” (25.4
cm) square hole (refer to Figure 9). The center of the square hole should match the centerline of the
horizontal pipe. Cut and frame the 10” (25.4 cm) x 10” (25.4 cm) hole in the exterior wall where the
vent will be terminated. Refer to Figure 8. If the wall being penetrated is constructed of non-combustible
material i.e. masonry or concrete, a 7 inches (17.8 cm) hole
is acceptable.
